BEA'IER FOR THRESHERS.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 20, 1914. Serial N 0. 826,033.

To all whom it may concern Be it known that I, FRANK IE'RI.AN,ZL citizenof the United States, and residing in Grafton, in the county of WValshand State of North Dakota, have invented a new and Improved Beater forThreshers, of whlch the following is a full, clear, and exactdescription.

My invention has for its object to provide a beater for threshermachines which is disposed above the grain pan and the straw rack, thebeater being constructed with a drum having annular grooves in which arejournaled rollers which engageand rec1procate pivoted beater stickswhich are prevented from lateral movement by the sides of the annulargrooves.

The drum has annular ribs between the grooves for engaging the straw tofree the grain.

Additional objects of the invention Will appear in the followingspecification in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts inall the views in which Figure 1 is a sectional elevation of a portion ofa thresher showing how my improvement is used; Fig. 2 is a sectionalplan view of my improvement; Fig. 3 is a sectional view of my beaterdrum; and Figs. 4 and 5 are sectional views showing how the beatersticks are raised periodically by the rollers disposed in annulargrooves in the beater drum.

By referring to the drawings it will be seen that the thresher 10 isconstructed with the usual concave 11 and theshing cylinder 12, thestraw passing from the concave 11 over the rack 13 to the straw carrier14 which is operated in the usual manner and which conveys the straw adistance above the straw rack 14*. Over this straw rack l4 there arepivoted one or more beater sticks 17, the beater sticks 17 beingfulcrumed at 18 to the brackets 19. The straw is deposited on the beatersticks 17 by the straw carrier 14. These beater sticks 17 are disposedin the annular grooves 20, the sides of which are formed by the circularflanges 21 on the beater drum 22. Secured to the flanges 21 andextending across the annular grooves 20 there are studs .23 on whichrollers 24 are mounted, the beater sticks 17 resting on one or more ofthese rollers 24 so that with the rotation of the drum 22 the beatersticks 17 will be raised periodically from their normal position whichis down wardly and rearwardly above the straw rack 14. In Fig. 4 I showbeater stick which has been raised to its uppermost position by one ofthe rollers 24 and in Fig. 5 I show in full lines a beater stick duringits up ward movement, the dotted lines 25 showing the position of thebeater stick when it has been fully raised by one of the rollers 24 andthe dotted rollers 24 showing the position of the rollers when thebeater stick 25 is at its uppermost position. The dotted lines 26indicate the position of the beater stick when it is at its lowermostposition and the dotted lines 24 show the positions of the rollers 24when the beater stick 26 is at its lowermost position. Disposed betweenthe circular flanges 21 and extending radially from the drum 22 thereare ribs 27 for engaging the straw and assisting the movement of thestraw rearwardly of the straw rack 14.

I prefer to dispose the rollers 24 in such a manner that one of thebeater sticks 25 will be raised when its neighboring beater sticks arepermitted to fall against the straw by the movement of the rollers 24which are disposed in the grooves in which the beater stick moves. Thisarrangement of the rollers 24 is indicated in Fig. 4 of the drawings.

lVith the rotation of the drum 22 the beater sticks will raise the strawto shake out the grainand even when the straw is damp the beater sticks17 spread the straw and free the grain. One or more drums 22 with theirbeater sticks may be used as desired. The drums 22 are rotated in anysuitable manner.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

1. In a heater for threshers, a straw rack, a drum disposed above thestraw rack, the drum having an annular groove, a pivoted beaterstickdisposed downwardly and rearwardly in said groove, and a member ormembers in the groove for raising the beater stick substantially to ahorizontal position.

2. In a beater for threshers, a drum having two circular flanges spacedapart to form an annular groove therebetween, a pivoted beater stickdisposed in the grooves, a member in the groove for engaging the beaterstick for operating the latter with the rotation of the drum, and radialribs on the drum at each side of the annular groove.

3. In a beater for threshers, a straw rack, a drum disposed above thestraw rack, the drum having an annular groove, a beater stick pivotedabove the straw rack and disposed downwardly and rearwardly in said andmeans for raising the beater groove,

horlzontal position.

stick periodically to a 4C. In a beater, a straw carrier, a drumdisposed in the rear of the straw carrier, the drum having annulargrooves and pivoted beater sticks, the pivoted beater sticks beingsubstantially straight and being disposed rearwardly and in the grooves,and members in the grooves for supporting the beater stickssubstantially at an incline of fifteen Copies of this patent may beobtained for five cents each, by addressing the degrees from ahorizontal position, and for raising the beater sticks periodically to ahorizontal position.

5. In a heater for threshers, a drum having an annular groove and radialribs at the sides of the groove, a pivoted beater stick disposed in thegroove and over the axis of the drum, and a member in the groove forengaging the beater stick for operating the latter with the rotation ofthe drum. 1

In witness whereof I have hereunto signed my name to this specificationin the presence of the two subscribing witnesses.
